Description

一种扩展装置 技术领域
本方案属于扩展电子设备功能的扩展设备技术领域，更具体地说，是涉及一种扩展装置。
 背景技术
USB Type-C接口近几年推出后，由于正反可插及支持快速充电，相比上一代USB接口还能更快地传输视频、音频、文件等数字信息，其具有多种功能，受到了广大消费者的欢迎，在电脑，平板，手机等电子设备上得到了迅速的普及。针对这些带USB Type-C接口的电子设备，厂商也推出了很多搭配带USB Type-C接口的电源适配器，拥有多个设备（电脑，平板，手机等）的消费者可能有多个电源适配器，这些过多的充电器仅仅只有充电功能，无形中是一种资源的浪费。
另外消费者在使用这些电子设备时也会发现平板电脑和手机只有1个USB Type-C接口或仅有USB Type-C接口，这对于办公或家用来说，USB接口是不够用的，如果要扩展的话，就只能另购快充，集线器(HUB)，扩展坞(Dock)等设备，对于携带和空间利用明显不足。
因此，现有技术存在的问题是电源适配器只提供单一的充电功能，且用户具有多个电源适配器，造成资源的闲置，需要提供相应的扩展电子设备以解决该问题。
 技术问题
本方案实施例的目的在于：提供一种扩展装置，用以解决现有技术中存在的电源适配器无法扩展功能的技术问题。

具体地，第一对接面11和第二对接面12设置于壳体1的不同的侧面上，避免电源适配器和线缆相互影响；或者第一对接面11和第二对接面12设置壳体1的同一侧面上，并且传输接口22和扩展接口23的位置间隔开预设距离，保证在电源适配器与扩展装置对接后，扩展接口23还可以与线缆进行连接。
在一个实施例中，第一对接面11设有用于固定电源适配器的固定组件13。电源适配器的接头与扩展装置的传输接口22对接后，利用固定组件13对电源适配器进行固定，防止在使用过程中电源适配器从扩展装置上脱落，造成连接失败或者损坏。
在一个实施例中，固定组件13为磁性件、卡扣件或者魔术贴件。利用磁性件将电源适配器吸附在扩展装置上，固定效果好并且易于拆卸；同样地可利用卡扣件固定电源适配器或者利用魔术贴件进行固定，固定方便并且易于取下。
请同时参阅图1和图2，在一个实施例中，壳体1包括用于收容接口组件2的第一容置壳101和用于收容电源适配器的第二容置壳102，第二容置壳102与第一对接面11连接。第二容置壳102的形状和尺寸适应于电源适配器，并且第二容置壳102的顶部开设有供电源适配器放入的开口15，电源适配器从该开口15放入于第二容置壳102内，并且电源适配器的接头与扩展装置的传输接口22对接。第二容置壳102避免在使用的过程中对接后的电源适配器受到碰触而导致传输接口22脱离接头，造成接触不良或者损坏；并且电源适配器收容于第二容置壳102内，使得两者接近一体化，更加美观大方。电源适配器的侧面可贴合于第二容置壳102的内侧壁，也可不贴合于第二容置壳102的内侧壁，并且在第二容置壳102和电源适配器之间可设置缓冲件，可在跌落时候保护电源适配器。
在一个实施例中，第二容置壳102包括侧板141，第一对接面11设于侧板141的内壁。
在一个实施例中，侧板141的数量为一个，侧板141抵于电源适配器的一侧面。用一个侧板141抵于电源适配器的一侧面，保护电源适配器。
在一个实施例中，侧板141的数量为两个，两侧板141相对设置或者两侧板141邻接设置。两侧板141围合形成一个收容电源适配器的空间，在电源适配器放入第二容置壳102中时，侧板141起导向作用，方便用户***第二容置壳102中，并且相对设置或者邻接设置的两侧板141可夹持电源适配器，进一步加固电源适配器，避免电源适配器在使用过程晃动。
在一个实施例中，侧板141的数量为三个，三个侧板141依次邻接。三个侧板141形成收容电源适配器的空间，并且保护电源适配器。
在一个实施例中，侧板141的数量为四个，四个侧板141依次邻接。四个侧板141形成收容电源适配器的空间，并且保护电源适配器。
在一个实施例中，第二容置壳102顶部设有用于供电源适配器的电源头露出的拔槽142。用户将电源适配器从第二容置壳中取出时，可夹持电源头，进而将整个电源适配器取出。
在一个实施例中，第二容置壳102顶部设有盖体16，即，其中一个侧板141的顶部设有盖体16。该盖体16在电源适配器放入第二容置壳102后，盖于第二容置壳102的开口15，防止电源适配器从第二容置壳102的开口15掉出。盖体与第二容置壳102的装配方式不限于滑条、卡扣或者翻盖等连接方式。在一个实施例中，盖体16与第二容置壳102铰接，即，其中一个侧板141与盖体16铰接。盖体16铰接于第二容置壳102上，打开盖体16，将电源适配器放入于第二容置壳102中，然后将盖体16盖于第二容置壳102上，利用扣合结构将盖体16固定于第二容置壳102上。
在一个实施例中，盖体16与第二容置壳102滑动连接。
请同时参阅图2和图5，在一个实施例中，第二容置壳102的顶端设有滑槽143，相对设置的两侧板141上均设有滑槽143，盖体16设有可滑入滑槽143的滑条161。两个滑槽143的槽口1431朝相反的方向设置，滑条161可滑动地卡于滑槽143中。滑条161沿着滑槽143的长度方向朝第二容置壳102外滑动，打开盖体16，可将电源适配器放入第二容置壳102中，然后再将滑条161沿滑槽143的长度方向朝第二容置壳102内滑动，盖合盖体16，将电源适配器固定于第二容置壳102中。
在一个实施例中，滑条还设有限位槽，滑槽设有可卡入限位槽的限位块。用户在滑动拉出盖体16时，为避免用户拉出过多，将盖体16完全与第二容置壳102脱离，盖体16容易丢失，因此设置限位块，限制盖体16的拉出长度，并且将盖体16限位在第二容置壳102上。
请同时参阅图3和图5，在一个实施例中，第二容置壳102的顶端设有卡槽144，盖体16设有可卡入卡槽144的卡块162。当盖体16完全盖合于第二容置壳102时，卡块162卡于卡槽144中，限制盖体16的滑出，当用户想打开盖体16时，使卡块162脱离卡槽144，盖体16可顺利滑出。进一步地，传输接口22包括USB Type-C接口，第一扩展接口23包括USB Type-C接口和USB Type-A接口或者Type-C接口和USB Type-A接口的其中一种，第二扩展接口24包括USB Type-C接口和USB Type-A接口和HDMI接口或者以上接口的其中一种或者几种。
